As illustrated in FIG. 3, the airbag 52 is accommodated in an airbag accommodation space S of the retainer 51 and is disposed below the meter 36. Specifically, the airbag 52 overlaps, from the lower side, the meter 36 and the wind screen 32 in a plan view from the upper side. It is thus possible to compactly dispose the airbag 52 using a space below the meter 36 and the wind screen 32. The airbag 52 is accommodated in the retainer 51 in a folded state. A lower end portion of the airbag 52 is connected to the inflator 53.

The motorcycle 1 includes an acceleration sensor (not illustrated) adapted to detect impact acting on the motorcycle 1. The acceleration sensor is electrically connected to a control unit (not illustrated) of the motorcycle 1, and the control unit is electrically connected to the inflator 53. The control unit determines whether or not to operate the airbag device 50 on the basis of detected acceleration. In a case in which the airbag device 50 is to be operated, the control unit operates the inflator 53 to discharge gas into the airbag 52. The airbag 52 is expanded by a gas pressure and is deployed upward.

The opening 51e of the retainer 51 is exposed on the front side from the cover opening portion 27b at the upper portion 27a of the front surface portion of the front cover 27. The cover opening portion 27b has such a size that the entire opening 51e is exposed. The cap member 54 is provided in the cover opening portion 27b.

The cap member 54 is attached to the retainer 51 by the inner peripheral surface of the cap peripheral wall portion 54b being fitted to the outer peripheral surface of the peripheral edge portion of the opening 51e.

Specifically, in an ordinary state (closed state) in which the wind screen 32 is set to be inclined rear-upward as illustrated in FIG. 3, the opening 51e is blocked with the cap member 54 and is covered and closed with the wind screen 32 from the front upper side. Also, in a state before the airbag 52 is deployed as in FIG. 3, the extending portion 54c of the cap member 54 abuts on the rear surface of the wind screen 32. Note that the extending portion 54c may be in proximity to the rear surface of the wind screen 32 instead of abutting on the rear surface of the wind screen 32.

In an opened state in which the wind screen 32 has swung forward around the hinge portion 41 as illustrated in FIG. 4, the wind screen 32 is separated from the opening 51e on the front side.

Referring to FIG. 4, once gas is discharged from the inflator 53, the cap member 54 is cleaved on the front upper side by the airbag 52 deployed upward, and the airbag 52 expands forward and upward through the opening 51e of the retainer 51 and the cover opening portion 27b. The cap member 54 pushes the wind screen 32 forward via the extending portion 54c at the time of the cleavage and causes the wind screen 32 to swing forward around the hinge portion 41. In this manner, the opening 51e of the retainer 51 is opened.

The airbag 52 exits the opening 51e forward and upward and is deployed upward along the rear surface of the wind screen 32.

In the present embodiment, since the opening 51e of the retainer 51 is opened by causing the wind screen 32 to swing, it is possible to dispose the opening 51e of the retainer 51 behind the wind screen 32. It is thus possible to compactly dispose the retainer 51 using a space covered with the wind screen 32.

The retainer 51 is provided on the front upper side of the head pipe 14 and is located near the upper body from the head to the breast of the passenger in the up-down direction. It is thus possible to appropriately protect the passenger even when the length of the airbag 52 in the up-down direction in a deployed state is reduced and thereby to reduce the size of the airbag device 50.

As described above, according to the present embodiment to which the present invention is applied, the airbag device 50 for the motorcycle 1 includes: the inflator 53; the airbag 52 adapted to be expanded by gas discharged from the inflator 53; and the retainer 51 accommodating the airbag 52, the airbag 52 is deployed upward from the opening 51e of the retainer 51, the retainer 51 is disposed in front of the head pipe 14 adapted to support the handle 23 for steering, the wind screen 32 is disposed above the retainer 51, and the wind screen 32 openably and closably covers the opening 51e of the retainer 51.

With this configuration, the wind screen 32 openably and closably covers the opening 51e of the retainer 51, and the airbag 52 can be deployed upward from the opening 51e in a state in which the opening 51e is opened. It is thus possible to compactly dispose the airbag device 50 at the front portion of the motorcycle 1 using the space covered with the wind screen 32.

Also, the headlight 33 disposed in front of the head pipe 14 and the meter 36 disposed in front of the handle 23 are provided, and the retainer 51 is disposed between the headlight 33 and the meter 36 in a side view of the vehicle.
